GPS uses tiny robots in space to find you! Imagine a group of friendly robots floating around the Earth. Each robot sends a message to your phone telling it how far away it is. Your phone listens to all these messages and figures out where it must be, like solving a fun puzzle with distances from four different friends.
Examples
- Your phone finds your way home by listening to four satellites telling it how far away they are.
- Your car knows when to turn right because of messages from satellites above.
